Hloov steelmaking calcium silicon Si40 Fe40 Ca10

Tom qab silicon-calcium alloy yog deoxidized, non-metallic inclusions nrog cov khoom loj dua thiab yooj yim rau ntab yog tsim, thiab cov duab thiab cov khoom ntawm non-metallic inclusions kuj hloov.Yog li ntawd, silicon-calcium alloy yog siv los tsim cov hlau huv si, cov hlau zoo uas tsis tshua muaj oxygen thiab cov ntsiab lus sulfur, thiab tshwj xeeb kev ua haujlwm steel nrog cov pa oxygen thiab cov ntsiab lus sulfur tsis tshua muaj.Qhov sib ntxiv ntawm silicon-calcium alloy tuaj yeem tshem tawm cov nodulation ntawm cov hlau nrog txhuas raws li qhov kawg deoxidizer ntawm lub ladle nozzle, thiab cov clogging ntawm lub nozzle ntawm tundish ntawm nruam casting |ua hlau.Nyob rau hauv cov hlau refining tshuab sab nraum lub cub tawg, silicon-calcium hmoov los yog core hlau yog siv rau deoxidation thiab desulfurization los txo cov ntsiab lus ntawm oxygen thiab sulfur nyob rau hauv cov hlau mus rau ib tug tsawg heev theem;nws tseem tuaj yeem tswj cov ntawv sulfide hauv cov hlau thiab txhim kho kev siv cov calcium.Hauv kev tsim cov cam khwb cia hlau, ntxiv rau deoxidation thiab purification, silicon-calcium alloy tseem ua lub luag haujlwm inoculating, uas pab tsim cov nplua-grained lossis kheej kheej graphite;ua rau cov graphite hauv grey cam khwb cia hlau tusyees faib, txo qhov nyiam ntawm whitening;thiab tuaj yeem nce silicon thiab desulfurize, txhim kho cam khwb cia hlau zoo.
